PROBLEM TO BE SOLVED: To provide a method for manufacturing a sulfide all-solid battery by which a sulfide all-solid battery improved in performance can be manufactured.SOLUTION: A method for manufacturing a sulfide all-solid battery having a positive electrode layer, a negative electrode layer, and a solid electrolytic layer disposed therebetween comprises: a coating step of coating a surface of a base material with a paste composition prepared by using a sulfide solid electrolyte, a substance which brings about the effect of increasing a viscosity, and a solvent to forming a coating film on the surface of the base material; a press step of pressing the coating film formed on the surface of the base material with a subject to transfer to kept in contact therewith; and a transfer step of transferring the coating film to a surface of the subject to transfer to by peeling off the base material after the press step. In the method for manufacturing a sulfide all-solid battery, the substance which brings about the
